In this talk I will give an overview of the Hall A Moller Polarimeter at Jefferson Lab and I will present recent results on the beam polarization measurements taken during the PREX II experiment.
The recently developed Jefferson Lab Hall-A moller polarimeter Geant4-based simulation [MolPol] is a vital tool in understanding the analyzing power of the polarimeter for parity experiments ranging from PREX-II at 1 GeV to future 11 GeV experiments. I'll discuss the application's role in the development of optics solutions, understanding of e- transportation through the polarimeter and the...
The international JEDI (Jülich Electric Dipole moment Investigation) collaboration is preparing a first-ever direct measurement of the deuteron Electric Dipole Moment (EDM), using the COSY storage ring at Forschungszentrum Jülich (Germany).
A new polarimeter is required to detect the very slow and minuscule polarization change with time: starting in 2016, we have designed, built and...
One aim for the new electron accelerator MESA is to measure the weak mixing angle in electron proton scattering to a precision of 0.14 %. The beam polarization significantly contributes to this measurement. The Møller polarimeter proposed by V. Luppov and E. Chudakov opens the way to reach a sufficiently accurate determination of polarization. At the moment the polarized atomic hydrogen target...
The P2 Experiment at the new Mainz Energy-recovering Superconducting Accelerator (MESA)
aims at measuring the weak mixing angle sin² θ_W at low Q² with high precision. Therefore
the polarization of the incident electron beam has to be known with a very high accuracy (< 0.5%).
Conventional Mott polarimeters are limited by uncertainties in the extrapolation and theoretical
calculations...
The Compton polarimeter at Jefferson Lab's experimental Hall A provides a continuous, non-invasive measurement of electron beam polarization via electron-photon scattering. The electron beam passing through the polarimeter intercepts green laser light stored in a Fabry-Perot cavity. Scattered electrons are detected in an electron detector while back scattered photons are detected in a GSO...
The Jefferson Lab Continuous Electron Beam Accelerator Facility’s experimental Hall A employs a Compton polarimeter to measure incoming beam polarization for parity violating electron scattering experiments. The polarimeter operates by amplifying green laser light in a Fabry-Perot cavity which then compton scatters off the incoming electron beam. The scattered photons are then passed through a...
